The traditional way to restore a tooth with an artificial crown takes several weeks and multiple office visits: from tooth preparation and impression molding to crown production by a dental laboratory, followed by adjustments and cementing. Now, there’s an alternative that reduces this process to a fraction of the time, and all from your dentist’s office.
Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) is a digital system that enables dentists to create dental restorations with laboratory-grade materials in minutes rather than weeks. As it continues to innovate, you’ll see more and more dentists investing in the new technology for their patients.
A crown restoration with CAD/CAM begins like any other with decay removal and preparation of the tooth. It diverges, though, from the traditional in how an impression of your teeth and gums is obtained: instead of rubber-like molding materials to create a physical impression, we lightly dust the mouth interior with a reflective powder. Using a scanning wand, the reflective powder allows us to capture multiple, detailed images of your mouth that the CAD/CAM computer transforms into an accurate three-dimensional model.
We use the model to first assess if the tooth has been effectively prepared for a restoration. If so, the design feature of the system will provide us with thousands of tooth forms to choose from to match with your natural teeth. You’ll be able to view the proposed size and shape of the new crown via computer simulation before signing off on the design.
Next is the actual manufacture of the crown that takes place right in the dentist’s office. A pre-formed block of ceramic material is inserted in the milling equipment where, following the pre-determined computer design, the milling heads carve the ceramic block. After milling, we fine-tune the crown surface and apply stains or glazes fired to create a life-like color and texture that matches your natural teeth. We can then adjust the crown in your mouth and permanently affix it to the tooth.
While much of the CAD/CAM system is automated, ultimate success still depends on the dentist’s expertise and artistry. CAD/CAM enhances those skills with greater precision and in much less time than traditional crowns. It’s certainly a growing option for many people to restore the form and function of decayed teeth.

Sometimes, looking at old pictures can really bring memories back to life. Just ask Stefani Germanotta—the pop diva better known as Lady Gaga. In one scene from the recent documentary Five Foot Two, as family members sort through headshots from her teen years, her father proclaims: "Here, this proves she had braces!"
"If I had kept that gap, then I would have even more problems with Madonna," Lady Gaga replies, referencing an ongoing feud between the two musical celebrities.
The photos of Gaga's teenage smile reveal that the singer of hits like "Born This Way" once had a noticeable gap (which dentists call a diastema) between her front teeth. This condition is common in children, but often becomes less conspicuous with age. It isn't necessarily a problem: Lots of well-known people have extra space in their smiles, including ex-football player and TV host Michael Strahan, actress Anna Paquin…and fellow pop superstar Madonna. It hasn't hurt any of their careers.
Yet others would prefer a smile without the gap. Fortunately, diastema in children is generally not difficult to fix. One of the easiest ways to do so is with traditional braces or clear aligners. These orthodontic appliances, usually worn for a period of months, can actually move the teeth into positions that look more pleasing in the smile and function better in the bite. For many people, orthodontic treatment is a part of their emergence from adolescence into adulthood.
Braces and aligners, along with other specialized orthodontic appliances, can also remedy many bite problems besides diastema. They can correct misaligned teeth and spacing irregularities, fix overbites and underbites, and take care of numerous other types of malocclusions (bite problems).
The American Association of Orthodontists recommends that kids get screened for orthodontic problems at age 7. Even if an issue is found, most won't get treatment at this age—but in some instances, it's possible that early intervention can save a great deal of time, money and effort later. For example, while the jaw is still developing, its growth can be guided with special appliances that can make future orthodontic treatment go quicker and easier.
Yet orthodontics isn't just for children—adults can wear braces too! As long as teeth and gums are healthy, there's no upper age limit on orthodontic treatment. Instead of traditional silver braces, many adults choose tooth-colored braces or clear aligners to complement their more professional appearance.
So if your child is at the age where screening is recommended—or if you're unhappy with your own smile—ask us whether orthodontics could help. But if you get into a rivalry with Madonna…you're on your own.

Henry Ford famously said a customer could have any color they wanted on their Model T “as long as it was black.” Those days are over—today’s cars and trucks come with a slew of options, and not just their paint color.
There’s something else with a wide array of possible options: your choice of toothbrush. Your local store’s dental care aisle has dozens of toothbrushes in a myriad of sizes, shapes and features. And many promise better hygiene outcomes because of their unique design.
It’s enough to make your head spin. But you can narrow your search for the right toothbrush— just look for these basic qualities.
Bristle texture. At this all-important juncture between brush and teeth, softer-textured bristles are better. That might sound counter-intuitive, but soft bristles are just as capable at removing bacterial plaque, that sticky tooth film most responsible for dental disease, as stiffer bristles. Stiffer bristles, on the other hand, can damage gums and cause recession. Also, look too for rounded bristles (gentler on the gums), and multi-leveled or angled ones for better access around teeth.
Size and shape. Toothbrushes come in different sizes because, well, so do mouths. Look, then, for a brush and bristle head that can comfortably reach all the teeth in your mouth. If you have problems with manual dexterity, choose a brush with larger grip handles. A brush that’s comfortable to use and easy to handle can make your brushing more effective.
ADA Seal of Acceptance. The American Dental Association tests hygiene products like toothbrushes. If they pass the association’s standards, the manufacturer includes the ADA Seal of Approval on their packaging. Not all submit their brushes for this evaluation, so the seal’s absence doesn’t necessarily mean a brush is of low quality. The seal, though, does tell you the product passes muster with dental professionals.
It often takes a little trial and error to find the right brush, but since you should change yours out every six months, it’s a small price to experiment. And, no matter how great the brush, it’s only as good at removing plaque as the hand that holds it. So, be sure you learn proper brushing techniques—that and the right brush will keep your teeth and gums healthy.
